AI Technical Summary

Benefits of technology

The patent is about a method for evaluating a person's risk of developing cardiovascular disease, such as heart disease and stroke, by detecting a specific polymorphism in the CD36 gene. This method can be used to identify individuals who have an increased risk of cardiovascular disease and can help healthcare providers and researchers better understand the genetic factors that contribute to the development of the disease. The method involves analyzing the person's DNA to determine if they have a specific polymorphism in the CD36 gene, which is associated with an increased risk of cardiovascular disease. This information can be used to develop a personalized risk profile for the person and to help prevent cardiovascular disease in its early stages.

Problems solved by technology

The presence or absence of such a polymorphism is correlated with risk of cardiovascular disease.
In some embodiments, the presence of a polymorphism in one or both alleles of a CD36 gene of the subject that is in linkage disequilibrium with a nucleotide corresponding to a position listed in FIG. 1 is correlated with an increased risk for cardiovascular disease.

Determination of the Haplotype Structure of the CD36 Locus

[0110]To determine the haplotype structure of the CD36 locus in Caucasians, 21 common SNPs (frequency≧0.05) were typed in 72 unrelated individuals from the general population. Study subjects were genotyped at polymorphic loci by means of PCR followed by dot blotting and allelic specific hybridization or single base extension / fluorescence polarization (AcycloPrime™-FP SNP Detection System) using a Wallac VICTOR2™ Multilabel Plate Reader (Perkin-Elmer).

[0111]Eight of the 21 SNPs were representative of the major linkage disequilibrium bins identified in the region between intron 3 and exon 14 by a resequencing project (available at pga.gs.washington.edu / data / cd36 / ). The other eleven were selected from the dbSNP database to cover the two alternative promoters (Sato et al., J. Biol. Chem., 277:15703-11 (2002)), the 5′ non-coding exons, and the 3′ UTR in exon 15. The 21 SNPs spanned a total of 63 Kb, resulting in a 3.0 Kb average s...

Demonstration of an Association Between FFA Levels and CD36 SNPs

[0114]The association between CD36 variants and metabolic traits was evaluated in 585 Caucasian residents of the Gargano area (East Coast of Italy). Their clinical characteristics are reported in Table 1. Subjects were recruited among the employees of the hospital ‘Casa Sollievo della Sofferenza’ (San Giovanni Rotondo, Italy), who had fasting plasma glucose Stress testing. Principles and Practice, F A Davis, Philadelphia. (1986)). The inter-and intra-assay coefficients of variation were 2.2% and 2.8%, respectively.

[0115]Continuous variables were compared among genotype groups by ANOVA using the PROC GLM procedure of the SAS software package (SAS Institute, Cary, N.C.). All analyses included gender and age as covariates. Fasting insulin, triglycerides, and FFA were analyzed after logarithmic transformation. The association between FFA levels and common (≧0.05) CD36 haplotypes was analyzed using the score statistics propo...

Demonstration of an Association Between CAD and CD36 SNPs

[0121]To determine whether the CD36 AAGIC haplotype was also associated with coronary artery disease (CAD), two populations of individuals with type 2 diabetes (defined according to the WHO criteria) were studied, one from Boston (n=197), the other from San Giovanni Rotondo, Italy (n=321). The study protocol and informed consent procedures were approved by the local research ethic committees. Each population included a group of CAD-positive cases and a group of CAD-negative controls. In the Boston study, the CAD-positive cases, defined as subjects who had a stenosis greater than 50% in at least one major coronary artery or their main branches, were recruited among type 2 diabetic patients who underwent cardiac catheterization at the Beth Israel Deaconess Medical Center (BIDMC) between Feb. 1, 2000, and Jan. 31, 2002. CAD-negative controls were Joslin patients (the Joslin Clinic serves as the BIDMC Diabetes Clinic) who were age...

CLAIM OF PRIORITY[0001]This application is a continuation in part of International Patent Application No. PCT / US2005 / 016370, filed May 10, 2005, and claims the benefit under 35 USC §119(e) to U.S. Provisional Patent Application Ser. No. 60 / 569,898, filed on May 11, 2004, the entire contents of which are hereby incorporated by reference.GOVERNMENT SUPPORT[0002]The work described herein was carried out, at least in part, using funds from the U.S. government under grants HL73168, DK60837, and DK36836 awarded by the National Institutes of Health. The government has certain rights in the invention.BACKGROUND[0003]CD36, also known as platelet glycoprotein IV or IIIb, is an 88 kDa membrane protein expressed on the surface of a wide variety of cell types, including adipocytes, skeletal muscle cells, platelets, endothelial cells, and monocytes / macrophages (Febbraio et al., J. Clin. Invest., 108:785-91 (2001)). Initially identified for its binding to collagen and thrombospondin (TSP-1) in pla...
